Manila, Philippines — The National Grid Corp. of the Philippines (NGCP)’s comprehensive grid enhancement program implemented months before the onset of the summer period proved to be beneficial for Luzon grid customers, who are continuing to enjoy uninterrupted delivery of power transmission services.
Surpassing the 2016 actual peak demand and the Department of Energy (DOE)’s 2017 peak demand projection, this year’s actual demand reached an all-time high of 10,054 Megawatts (MW) on 09 May 2017 at 2:27PM. The total available capacity then was at 11,444 MW, allowing an operating margin of 1,390MW.
Luzon grid customers, however, did not feel the effect of the steep rise in demand as improvements on the transmission facilities designed precisely to better manage the grid during peak load periods were implemented by the grid operator in anticipation of this year’s record breaking power demand. In particular, NGCP increased protection for its critical substation equipment, enhanced operating measures of transformers at its San Jose, Dasmariñas, Bolo, and Tayabas 500-kiloVolt (kV) substations, and coordinated adjusted capabilities of large generating units such as Sual, Masinloc, GN Power, Pagbilao, Ilijan, and Sta. Rita/San Lorenzo.
Potential low voltage problems were also eliminated through the timely energization of capacitor banks, allowing NGCP’s Luzon System Operations to maintain the system voltage level within the normal limits, even at the height of the summer season.
“NGCP is pleased to report that through the foresight of our technical team, we were able to prepare and address early on any potential grid stability issues for the summer period, even as the demand breached DOE’s projection. With this foresight, our customers enjoyed reliable and uninterrupted quality of power,” stated the company.
As the peak demand season for 2017 nears its end, NGCP seeks support for its projects aimed at strengthening the grid for the coming years, as it also appeals for better management of power supply, particularly scheduling additional energy sources to increase the thinning supply. “We want to be able to accommodate the continually growing demand and supply for power in Luzon, not just during the summer season. The support of local government units (LGUs), government agencies such as DILG, DENR, the Laguna Lake Development Authority (LLDA), and the public, will enable NGCP to complete these projects on-time, if not ahead of schedule,” appealed NGCP.
Part of NGCP’s load growth projects for Luzon are focused on reinforcing the Western and Eastern Manila backbone, with critical components such as the 230-kV Pasay Substation, Taguig-Taytay 230-kV line, and a 500-kV Taguig Substation. “These locations have been identified, through careful technical research and feasibility studies, to be the most strategic, being close to the center of load growth. Delaying the implementation of critical projects, like the Pasay Substation, will lead to overloading issues and possible power interruptions within Metro Manila,” stated the company.
NGCP added that, “Power demand for Luzon will keep on growing in the years ahead. It is our mandate to ensure that the grid is able to deliver electricity from the generators, to wherever it is needed. We do this by continuously improving the grid and putting in place the technological advances necessary to keep NGCP ahead of the curve. We will deliver. This is our promise.”
NGCP is a Filipino-led, privately owned company in charge of operating, maintaining, and developing the country’s power grid, led by majority shareholders Henry Sy, Jr. and Robert Coyiuto, Jr.
